True Velocity composite-cased ammunition has been selected for the U.S. Army’s Next Generation Squad Weapon modernization program.

True Velocity’s 6.8mm composite-cased cartridge was submitted as part of an overall NGSW weapon system in partnership with General Dynamics Ordnance and Tactical Systems and firearm manufacturer Beretta Defense Technologies.

This ammunition has a metal base that is integrated with the polymer body. All the True Velocity cartridges that were shown before were replicating the external dimensions of their brass counterparts. However, the NGSW submission has a different design of shoulder and neck areas. As you can see, instead of a traditional shoulder and neck, the case has a rather small step from the case body to the bullet. I assume that step is designed to provide a headspacing point. I think the bullet should be supported inside the case. This design should be more reliable due to the elimination of a conventional case shoulder and neck which arguably has been the weakest point of polymer cased cartridges.

Bold/italics added by myself. It almost has a hint of the Weatherby rounded shoulder with an inverse right at the support point. Could be the next big thing!

The Army announced on the evening of August 29th, 2019 that 3 companies were chosen to proceed to phase 2 of development of the Next Generation Squad Weapons with 6.8mm ammunition. The companies are (no surprises):
1) General Dynamics-OTS Inc. (OTS = Ordnance & Tactical Systems).
OTS has teamed up with True Velocity which has the True Velocity Composite Munition. True Velocity has been working on polymer case - metal cartridge head ammunition for some time.

True Velocity ammunition is NOT (yet) the type of ammunition chosen for the NGSW, but is in the running.

The confusion here probably arises from a press release from True Velocity on September 6, 2019 in which they seem to imply their ammunition was the only one chosen for the NGSW program.

The press release is shown below, note the title and opening sentence which I highlighted:

U.S. Army selection for NGSW

U.S. ARMY SELECTS TRUE VELOCITY COMPOSITE-CASED AMMUNITION FOR NEXT GENERATION SQUAD WEAPON PROGRAM

GARLAND, TX – True Velocity composite-cased ammunition has been selected for the U.S. Army’s Next Generation Squad Weapon (NGSW) modernization program. True Velocity’s 6.8mm composite-cased cartridge was submitted as part of an overall NGSW weapon system in partnership with General Dynamics Ordnance and Tactical Systems and firearm manufacturer Beretta Defense Technologies.

True Velocity’s proprietary 6.8mm case design will provide end users with significant logistical and operational advantages over traditional brass-cased ammunition, including substantially increased effective range and muzzle energy, drastic reduction in cartridge weight and enhanced accuracy. The combination of True Velocity’s ammunition with the General Dynamics OTS weapon submission results in a state-of-the-art weapon system capable of long-range lethality, short recoil impulse, significant ballistic improvements and enhanced operational effectiveness for the soldier.

“True Velocity’s 6.8mm composite case design produces a level of performance, consistency and efficiency never before seen in small arms ammunition,” said Chris Tedford, president and chief operating officer for True Velocity. “Combining True Velocity’s innovation and technology with the expertise of General Dynamics OTS and Beretta results in a weapon system solution that exceeds NGSW requirements and provides the U.S. Army with a definitive edge on the field of battle.”https://www.truevelocityinc.com/media-center/us-army-selection-for-ngsw/

The fact is their ammunition is one of three types of 6.8mm ammunition that was chosen to proceed to PHASE 2 of NGSW development
